1971-1973年间,我在浙西南做过一些中生代含煤地层工作。该区中生代火山岩广泛分布,厚度巨大,侏罗纪的三组含煤地层,其中一组位于火山岩系之下,称乌灶组,另两组实为火山岩的夹层、称砻铺组和毛弄组。三组地层盛产植物化石,它们的植物分子组合显示植物上的进化关系。从浙西南锥叶蕨-拟刺葵(Coniopteris-Phoenicopsis)植物 During 1971-1973, I worked on some Mesozoic coal-bearing strata in southwestern Zhejiang. The Mesozoic volcanic rocks in the area are widely distributed and have huge thickness. Three sets of coal-bearing strata of Jurassic, one of which is under the volcanic rock series, are called the Wuzao Formation and the other two are intercalated layers of volcanic rocks. group. The three formations are rich in plant fossils, and their combination of plant molecules shows the evolutionary relationship on the plant.
